SLB-25.4B-30PIR1 25.4 mm Dia. x 31.2 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-25.4B-30PIR1 is a high-quality lens from OptoSigma, designed with a 25.4 mm diameter and a focal length of 31.2 mm. This lens is made of n-bk7 schott material, a popular choice for its excellent optical properties and durability.
The lens features a double-convex geometry, meaning it has two spherical surfaces that curve outwards. This design is often used to increase the optical power of the lens and reduce spherical aberration. The lens has a thickness of 1.8 mm at the edge and 7.2 mm at the center, providing a robust structure while maintaining a sleek profile.
The SLB-25.4B-30PIR1 is coated with opt ir1 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, particularly within the wavelength range of 633-1064nm. This makes the lens ideal for applications such as laser systems, optical imaging, and machine vision.
